Modeling will help researchers predict where cancer might spread in patients, better screen them
can be a particularly deadly one as it can quickly spread to some parts of the body once it metastasizes (once tumor cells enter the bloodstream). But the process of metastasis is poorly understood.
Looking to model the process researched at the
University of Southern California
emulated the underlying mechanics of Google Inc.'s (
Page Rank algorithm
and the Viterbi Algorithm (another popular algorithm used in GSM cell phone networks using probabilistic Markov chain-driven convolution) to model the spread of the cancer.
They found that the adrenal gland and kidney act as lung cancer cell "spreaders" distributing tumor cells around the body. By contrast, when infiltrated by tumor cells the regional lymph nodes, liver, and bones acted as "sponges" and did not significantly spread around the disease.
To get data for the model, the researchers used autopsy information on essentially untreated patients. They used data from 163 lung cancer patients in the New England area, from 1914 to 1943. In this era effective radiation therapies and chemotherapies did not exist, so the disease essentially spread unchecked.

There's growing interest in the medical field to use mathematical models to predict the spread of cancer. By using past data, doctors treating a particular kind of cancer can keep their eye out for where it might spread -- and which locations it would be most dangerous for it to spread to.

are they trying to imply google is a cancer?

since they are using google's methods.. are they not in effect implying google IS a cancer?
